This page contains a list of guidelines concerning naming conventions for categories. If you wish to propose a new naming convention for categories or modify an existing convention, please do so on the talk page.

Naming conventions

When naming a category, one should be particularly careful and choose its name accurately. Moving non-conventionally categorized pages to another category name (see {{Category redirect}}) imposes an additional overhead – an edit for each article and subcategory.

General conventions

  • Standard article naming conventions apply; in particular, do not capitalize regular nouns except when they come at the beginning of the title.
  • Names of topic categories should be singular, normally corresponding to the name of a Wikipedia article. Examples: "Law", "France", "Hillary Clinton".
  • Names of set categories should be plural. Examples: "Writers", "Villages in Poland".
  • Avoid abbreviations. Example: "Category:Military equipment of World War II", not "Category:Military equipment of WW2". However, abbreviations that have become the official or generally used name (such as NATO) should be used where there are no other conflicts.
  • Do not write the category structure in names. Example: "Monarchs", not "People – Monarchs". This includes creating categories that are subpages of other categories.
  • Choose category names that can stand alone, independent of the way a category is connected to other categories. Example: "Geography terminology stubs", not "Terminology" (a subcategory of "Geography stubs").
  • As with lists, avoid descriptive adjectives such as famous, important, or notable in category titles.
  • Particularly for technical subjects, use words and phrases which exist in reliable sources, so that those sources may be used to support inclusion of articles.
  • When an article topic requires disambiguation, any category eponymously named for that topic should include the same form of disambiguation, even if no other articles are likely to have an eponymous category.

Special conventions

Categorization of people

  • Avoid abbreviations. Exceptions should be rare, and explained in all member pages.
  • Avoid names that are too long or too short. Short, simple names are preferred for categories. It is possible to deviate from this principle for clarity and neutrality, but don't exaggerate on length or complexity of category names.

Neutrality

  • Use gender-neutral category names, unless there is a distinct reason and consensus to do otherwise. In that case, please specify the reason on the category page, and record the consensus on its associated discussion page.
    Example: instead of a category for "Kings" and a different category for "Queens", use Category:Monarchs.
  • Always try to use the most generic neutral name. Some categories can be used in a stigmatizing way.
    Example: "Prostitutes" is a better name for a category than "whores". "Sex workers" might work even better for a category name, as more gender-neutral.

Nationality and occupation

Heritage

The standard form for categories by ancestry, culture, or ethnicity is "FOOian people of BARian descent", where "FOOian" is the person's nationality (country of citizenship) and "BARian" is the person's ethnic ancestry (such as Category:Irish people of Ghanaian descent and Category:American people of German descent).

Residence

For categorizing people by residence, the form is People from Foo (not "Natives of Foo"). Where the commonly used English name for residents of a place is well-known globally (usually the original place of that name), Fooite demonym categories should be {{category redirect}}ed to People from Foo, assisting in automated categorization (for example, Category:New Yorkers).

Place of burial

For categorizing people by place of burial, the category name is in the form Burials at Foo Cemetery.

Time periods

By convention, a category name designating a time period with a number (in Arabic numerals) represents a calendar year in the Common Era. For years BCE, the format is "<year number> BC", for example Category:220 BC deaths.

Categories for people by century should be named Category:xx-century foos or Category:xx-century BC foos.

Categories by country

All categories whose subcategories are categories by country (roughly all categories that are members of Category:Categories by country) shall have a per-category naming convention which will apply to all of their subcategories. These naming conventions, their guidelines and their exceptions are listed here. Non-conformance to these naming conventions shall be treated as a criterion for "speedy category renaming" as defined on WP:CFD.

Events

Categories regarding events in countries (along with years and time) are named "... in country." This guideline applies to:

Millennia - Centuries - Decades - Years - Establishments - Disestablishments

Manufactured objects

Categories of permanently located manufactured objects by country are named "... in country". This guideline applies to:

Airports - American football venues - Amusement parks - Archaeological sites - Art museums - Association football venues - Athletics (track and field) venues (mostly named "athletics" as per non-U.S. usage) - Baseball venues - Basketball venues - Bridges - Buildings and structures - Casinos - Castles - Cathedrals - Cemeteries - Churches - Cities - Cricket grounds - Forts - Gardens - Ghost towns - Golf clubs and courses - Horse racing venues - Hospitals - Hotels - Indoor arenas - Libraries - Monasteries - Motorsport venues - Mosques - Museums - Palaces - Parks - Prisons - Railway stations - Reservoirs - Roads - Rugby union stadiums - Schools - Shopping malls (or shopping centres, based on local usage) - Skyscrapers - Sports venues - Theatres - Towns - Universities and colleges ("Universities" categories are also legitimate in countries where universities and colleges are distinct, i.e. most countries, and are often a subcategory) - Villages - World Heritage Sites - Zoos

Landforms

Categories of landforms by country are named "... of country". This guideline applies to:

Landforms (top category) - Beaches - Hills - Islands - Lakes - Mountains - Mountain passes - Mountain ranges - Peninsulas - Rivers - Volcanoes

Companies

By-country subcategories of all <company type> by country categories are named ... of country. This guideline applies to:

Airlines - Banks - Book publishing companies - Companies - Defunct companies - Engineering companies - Financial services companies - Insurance companies - Manufacturing companies - Retail companies

State-based topics

Categories of topics usually in the domain of the state are named "... of country".

Administrative divisions - Foreign relations - Government - Military - Military equipment - Military units and formations - Municipalities * - National parks - Postal systems - Protected areas

  • Administrative divisions take the "of" form and settlements take the "in" form. Municipalities are usually found in non-English speaking countries as third tier administrative divisions covering the whole country including rural areas. In most cases, there are separate designations for settlements such as cities and towns. However where the designation "municipality" is used solely for urban settlements (example, Romania) or where it is the only official designation for cities and towns (example, Spain), the category takes the "in" form.

Political office-holders

By country subcategories of <political office> by country categories are named:

  • ... of country for those concerning holders of a specific office with jurisdiction over a country
  • ... in country for those that group offices of a certain type, operating within a country

This guideline applies to:

Political office-holders - Heads of government - Heads of state - Legislators - Government ministers (or "cabinet secretaries" if that is local usage) - minister lists - Presidents - Prime ministers

  • ... of places in ... for specific jurisdictions within a country, province, state, or equivalent
  • ... of place for the specific jurisdiction

This guideline applies to:

Mayors

Sport

By-country subcategories of all <sport name> by country categories are named ... in country. This guideline applies to:

Athletics - Association football (Australia, Canada and USA: "soccer") - Baseball - Basketball - Cricket - Cycle racing - Golf - Horse racing - Ice hockey - Motorsport - Rugby league - Rugby union - Sport (or sports if that is local usage) - Teams - Tennis

Miscellaneous "of country"

Subcategories of these categories are named "... of country".

Cinema - Coins - Demographics - Economies - Environment - Fauna - Geography - History - Languages - Natural history - Politics - Ships - Trade unions - Weapons

Miscellaneous "in country"

Subcategories of these categories are named "... in country".

Aviation - Business - Capital punishment - Communications - Crime - Disasters - Education - Ethnic groups - Health - Human rights - Landmarks - Law enforcement - Mass media - Nature conservation - Political parties - Populated places - Public holidays - Rail transport - Religion - Science and technology - Television - Tourism - Transportation (or transport if that is local usage)

Miscellaneous "involving country"

Subcategories of these categories are named "... involving country".

Battles - Military operations - Naval battles - Sieges - Wars

Miscellaneous

Aircraft ("manufactured by Foo") - Charities ("based in Foo") - Environmental organizations ("based in Foo") - Newspapers ("published in Foo") - Organizations ("based in Foo")

Undecided by country

The convention for these categories is yet to be decided. See the talk page for details. These will be moved up as consensus develops.

Films - Magazines - Law (currently mostly "Fooish law")

Technical categories

  • Images use the form "Images of country".
  • Lists use the form "Country-related lists"
  • Stubs use the form "Country stubs".

How to name the country

For "of country" and "in country" categories, the name of the country should appear as it does in the name of the article about that country, with a lowercase "the" if needed for grammatical purposes. Non-sovereign, disputed, supranational, and historical countries and geographic equivalents may be included if the articles to be categorized require it. For reference, see List of sovereign states, List of dependent territories, and the following list.

In category naming, country names should not be abbreviated (except to the extent that they are already in their respective article titles - for example, "United Kingdom", but not "UK" or "United Kingdom of Great Britain and Northern Ireland").

(Note: Links to articles are shown only for reference; links obviously cannot appear in the actual title of a category.)

Dealing with overlaps

When historical and political complexities (such as mergers and splits) create articles that belong to two countries, do not create a "Foo of X and Y". Instead, list articles in both "Foo of X" and "Foo of Y"; for example, "Foo of Russia" and "Foo of the Soviet Union", not "Foo of Russia and the Soviet Union". The same applies for geographic features that cross national borders, for example "Foo of the United States" and "Foo of Canada", not "Foo of the United States and Canada".

Categories by nationality

All categories whose subcategories are categories by nationality (roughly all categories that are members of Category:People by nationality or Category:Works by nationality) shall have a per-category naming convention which will apply to all of their subcategories. These naming conventions, their guidelines and their exceptions are listed here. Non-conformance to these naming conventions shall be treated as a criterion for "speedy category renaming" as defined on WP:CFD. Changing these conventions shall require a consensual discussion either directly at WP:CFD or publicized there.

Biographies

Subcategories of these categories are named "nationality ...".

Murderers - Musical groups - People by nationality and occupation - People by occupation and nationality - People

Cultural topics

National subcategories of these categories are named using the nationality rather than the country name, as they follow the national diasporas. However, the container categories are named "by country", e.g. Category:Art by country and Category:Culture by country.[1]

Art - Cuisine - Culture - Literature - Music - Plays

Note that many other sub-topics of "Society" are named using the country name, and so are some cultural topics e.g. Architecture and Classical music.

How to name a nationality

A list of adjectival forms of place names is available on Wikipedia. In situations where multiple adjectives are possible for a particular nationality (e.g., Argentine vs. Argentinean), discussions at categories for discussion have frequently opted for one alternative over another to ensure consistency in category naming. Note that the singular-form demonym and adjective for many nationalities are not interchangeable. (i.e., Icelander vs. Icelandic; New Zealander vs. New Zealand). Most category names use the adjectival form, not the noun-form demonym.

Some states do not possess unambiguous (i.e., "Congolese" for Democratic Republic of the Congo) or universally-applicable (i.e., "Bosnian" for Bosnia and Herzegovina) adjectives. In these circumstances, the format "Country FOO"—where Country is the unamended name of the country—has been selected for use.

The list below reflects the most recent consensuses on what form to use for particular nationalities. These adopted forms may be subject to change by consensus and proposals to do so can be made by nominating the affected categories at categories for discussion. References are included to discussions that have discussed particular name formats.

Current nationalities

Former nationalities

In general, the formats for people of former nationalities is less settled. The list below represents examples which are reasonably well settled. Many categories for people of former nationalities with a compound name use a "FOOs from Country" or "FOOs of Country" format.

Works of art categories by artist

All categories whose subcategories are categories by creative artist (roughly all categories that are members of Category:Works by artist) shall have a per-category naming convention which will apply to all of their subcategories. These naming conventions, their guidelines and their exceptions are listed here. Non-conformance to these naming conventions shall be treated as a criterion for "speedy category renaming" as defined at WP:CFD. Changing these conventions shall require a consensual discussion either directly at WP:CFD or publicized there.

Music by composer

Subcategories of these categories are named "Compositions by [composer]".

Compositions by composerOperas by composerSymphonies by composerSongs by composer

Music by performer

Subcategories of these categories are named "[Performer] works".

Albums by artistSongs by artist

Visual arts

If there is only one type of work with articles, the subcategory is "[type of works] by [Artist]", e.g., "Paintings by Foo". A "Works by Foo" category is only needed if there are multiple categories for different types (paintings and drawings, for example).

Paintings by artistSculptures by artist

Architecture

Subcategories of these categories are named "[Architect] buildings", with exceptions for architects involved in more than one type of work.

Buildings and structures by architect

Literature

Subcategories of these categories are named "[Works] by [writer]".

Works by writerNovels by writerBooks by writerEssay collections by writerEssays by writerPicture books by writerPlays by writerPoetry by writerShort stories by writerShort story collections by writer

Stage and screen

Subcategories of these categories are named "[Works] by [person]".

Films by directorFilms with screenplays by writerPlays by writerTelevision shows by writer

Name of the artist

The name used should match the name of the biography article about the person, including any disambiguator, e.g. Category:Books by Peter Carey (novelist). The only exceptions are categories for visual arts, where the name used for the artist may instead match usage within the articles on the works; e.g. Category:Paintings by Sergei Ivanovich Osipov does not have to follow the article name Sergei Osipov (artist).[113]

Works of art categories by subject

Categories by the subject which is depicted follow the usual naming for that subject within articles and citations (including spelling and capitalisation), rather than the name of the Wikipedia article on the topic. For example:
